In pole beans, green pods (g) are a dominant trait, while yellow pods (g) are a recessive trait. a bean plant with a gg genotype is crossed with a second plant that has the gg genotype. if this cross produces 500 offspring, approximately how many of the offspring will have green pods? a.0 b.125 c.250 d.500

D (500)

Explanation:

This is a typical monohybrid cross involving one gene coding for pod color in pea plants. The allele for green pods (G) is dominant over the allele for yellow pods (g). This means that allele G will mask the expression of allele g in a combined allelic state.

In a cross between a pea plant that has a GG genotype i.e. homozygous dominant and a pea plant with gg genotype i.e. homozygous recessive, all offsprings will possess a heterozygous genotype (Gg). Since G allele (green) will mask the expression of g allele (yellow), all the offsprings will have phenotypic green pods.

Hence, if the cross produces 500 offsprings, approximately all 500 offsprings will have green pods (Gg)
